Sized From Our Install Log and Your Load Calc
Our install log clusters hard at 3 and 4 tons, which is what the typical Silicon Valley home actually needs. But “typical” is where sizing mistakes hide: an oversized AC short cycles and dies young, and an undersized one runs all day and never catches up. So we run a load calculation on your house, covering ductwork, insulation, and sun exposure, instead of copying whatever was installed last time.
Real numbers from our own jobs: typical full replacements run between $1,683 and $10,392 installed. The estimate is free, and more than half of the homeowners who get one from us go ahead with the work. We’d rather earn that with an honest quote than a hard sell. We’re a Trane TCS Select dealer (listed on Trane’s own dealer locator), with a three-year labor warranty on every install.
4 Signs It’s Time for a New AC
It’s 12-15+ years old
Compressors and coils wear out. Past this age, repair money is usually better spent on efficient new equipment.
Repairs keep stacking up
Two or three service calls a season means the system is telling you something. We’ll show you the math either way.
It still uses R-22 refrigerant
US production and import of R-22 ended January 1, 2020 under the EPA phaseout, so even small leak repairs are expensive. Replacement usually wins.
Uneven cooling and high bills
Older single-stage systems can’t match the SEER2 efficiency standards the Department of Energy set in 2023. The energy savings help pay for the upgrade.

Frequently Asked Questions
How much does a new AC cost installed?
From our own job data: typical full replacements run between $1,683 and $10,392 installed depending on size and ductwork. The estimate is free and itemized.
What size AC do I need?
Most Silicon Valley homes land at 3 or 4 tons, which is where our install log clusters. But the right answer comes from a load calculation on your house, not a rule of thumb.
How long does an AC installation take?
Most straightforward replacements are done in a day. Add ductwork or electrical changes and it can stretch to two.
Which AC brands do you install?
We’re a Trane TCS Select dealer, and Trane is the brand we install most. We also install Day & Night, Lennox, Bryant, and Mitsubishi for ductless. No online-purchased units; manufacturers won’t honor those warranties.
What warranty comes with a new installation?
Three years on labor, plus the manufacturer’s equipment warranty.
